Hello,
I have some trouble accessing elixir maps, I didn’t figure out the way to because there is 3 ways :
body = %{
test: value
}
Do we access the "test field by :
- body[“test”
or - body[:test]
or
body.test
what is the difference between the 3 ways ?
thanks

Hey @xgeek116
This one won’t work, because it looks for a key that is
"test"."test"is a string, but your key is:testwhich is an atom.This will work and return the value. If you put in a key that does not exist in the map like
body[:hello]it will returnnil.This will also work and return the value. If you use a key that does not exist like
body.helloit will raise an exception.
